text formatting in sign dialog old vs new UI

[TrejGun]

in old UI there were line breaks in sign dialog

const message = "Text \n\n\n text";
window.web3.currentProvider.sendAsync({
      method: "personal_sign",
      params: [message, from],
      from
}, () => {});

but in new UI its missing

may be you have to add

    white-space: pre-line;

also non-latin chars are not displaying properly
this is Chinese language

[TrejGun]

probaly chinese language is not your issue

const message = "0x" + Buffer.from("言", "utf8").toString("hex");

works just fine
